Float Lifts Bottled Straw

Float Lifts Bottled Straw

December 1963…

Made short enough to fit inside a capped soda bottle, this plastic (or plastic-coated) straw would rise to sipping height when the bottle was opened. A bell-shaped float would supply lift, rising on gas bubbles. To sink the float when the bottle was being filled, the inventor suggests filling it with ice or sugar.
